Differentiated Predictive Fair Service for TCP Flows

Overview The majority of the traffic (bytes) flowing over the Internet today have been attributed to the Transmission Control Protocol (TCP). This strong presence of TCP has recently spurred further investigations into its congestion control mechanism and its effect on the performance of short and long data transfers. This paper investigates the interaction among short and long TCP flows, and how TCP service can be improved by employing a low-cost service differentiation scheme. Through control-theoretic arguments and extensive simulations, it shows the utility of isolating TCP flows into two classes based on their lifetime/ size, namely one class of short flows and another of long flows. With such class-based isolation, short and long TCP flows have separate service queues at routers.

Peter Cochrane's Blog: Fat cat telcos are killing the net

Yes, it all works to some degree some of the time but continually increasing the number of VoIP and videoconference calls, radio and TV broadcasts just creates congestion, increased latencies and ultimately one meltdown after another.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
